Fierce rivals Dereck Chisora and Tyson Fury collide in the biggest heavyweight grudge rematch in recent years with the winner earning the right to face Wladimir Klitschko for the WBO Heavyweight Championship of the World.

"Chisora's actions were criminal and shouldn't be tolerated," alleges Wladimir Klitschko. Wladimir, the younger brother of Vitali, is viewed by most insiders as the universally-recognized heavyweight champion.

Heavyweight champions Vitali Klitschko (43-2, 40 KOs) and little brother Wladimir Klitschko (56-3, 49 KOs) have been ruling over the former glamour division of boxing collectively since October of 2008, when 'Dr. Iron Fist' came out of retirement to take the WBC title from Nigerian Samuel Peter.

Robert Helenius 17-0 (11) claimed the vacant European Heavyweight title in Helsinki tonight in controversial circumstances, the judges awarding the home fighter a 115-113, 113-115, 115-113 split decision over Britain's Dereck Chisora 15-2 (9).
